UNITED STATES PATENT OFFICEQ RENHFLDO SOLANO, OF BROOKLYN, NEWV YORK.

SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 353,271, dated November23,1886,

Application filed August 28, 1886. Serial No. 212,050. (No'modcL) To aZZwhom it may concern.-

Be it known that I, RENALDO SOLANO, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York,haveinvented anew and useful Improvement in Spark-Arresters, of whichthe following is a specification, reference being bad to theaccompanying drawings, forming a part of the same, in which-- Figure 1is a longitudinal section of the smoke box and pipe of a locomotive withmy improvement; Fig. 2, a cross-sectional View showing the lowerswinging wire-cloth frame and its connections to the boiler; Fig. 3, a

cross-sectional view of the upper arresters. Figs. 4 and 5 are views indetail of the swinging wire-cloth frame; and Fig. 6, a view in detail,showing the trap in the upper spark-arrester as shown in Fig. 1.

Similar letters of reference indicate corre sponding parts in theseveral figures.

The object of my invention is to arrest the spark in a locomotivewithout diminishing the area of draft in the same, and it consistsinsuch a novel relative arrangement of the arresters that permit a freeescape of the products of combustion, as hereinafter more particularlydescribed.

In the drawings, A represents the extension smoke-box of a locomotive,in which a plate, 13, is fastened to the end of the boiler O, and to thesides of the smoke-box A. Upon the under side of the plate B wire-clothframes D and E depend about half-way across the depth of the smoke-boxA.

F is a wire-cloth frame projecting upward from the bottom of thesmoke-box, about mid way of the depending wire-cloth frames D, extendingabove the bottom of said frames, and hinged or pivoted to the side ofthe smokebox, so that it can be elevated to the position shown in dottedlines, for the purpose hereinafter explained. Upon the bottom of thesmoke-box an angle-plate is attached, to stop 5 the movement of theswinging frame F, which is fastened in its vertical position by pressingthe hook 1) into the discharge-pipe c.

G represents the upper spark-arrester, com; posed of a wire-cloth frame,which occupies the full upper half of the smoke-box and is fitted with awire-cloth trap, arranged centrally, swung on hinges d, and providedwith a suitable catch, 6, for holding the same in place.

I he swinging frame Fhas an upper cornice or plate, f, with pivots g,whichare journaled in a casting, h, the latter being slotted from thebearings, so that the frame F can be removed by simply raising it out ofthe bearing socket i.

Having now referred to the various parts, I I will proceed to describethe operation.'

The fire and sparks emitted from the horizontal fire-tubes will impingeagainst the plate B and the first spark-arrester, D, and the largersparks will be deflected and fall to the bottom of the smoke-box A; butas the sparkarrester D only occupies one-half of the area of the passagethe fire and sparks will consequently escape past it and meet the secondarrester, F, which will not allowany to pass unless drawn above theframe, by the draft, which in turn is met by the arrester E, whichdeflects all the sparks that are too large to pass through to thebottom, and all that remains will meet the finer screen or arrester G,which sustains the draft only through the wire-cloth covering.

In case, in the arrangementshown, the sparks should fill up the spacebefore the screen or arrester F, there will always be more clearance orspace than the area of the tubes of the boiler either below the screenor arresters D and E or above the screen or arrester F, and whereby thedraft is never impeded.

For cleaning out the sparks, the frame F is elevated and the catch bhooked, as at k, or to an eyebolt, Z, as indicated in the drawings, andthe dead sparks at the bottom are drawn to the discharge-pipe 0, whileaccess to the upper exhaust-chamber is had through the trap in thearrester G. a

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. A chamber into which the products of combustion are discharged,provided with a partitionplate, B, depending foraminous or wire-clothframes D and E, and projecting inraminous' plate or partition G, fittedwith a terposcd foraminous 0r wire-cloth frame F, for central trap ofsimilar material, substantially 10 the purpose specified. as and for thepurpose specified.
